Complaint Review: Toshiba

I have ut 2 years old Toshiba Satellite Laptop model L755-S5306. It comes installed with Toshiba PC support site link and everynow and then you get pop-up from Toshiba about software updates for our system. Most of the time I ignore them but just this time I decided to click and install it because my PC was running slightly slower I thought this will only help. Well while downloading and installing the update the laptop screen froze with message "VERIFY ERROR". I think this happened to be BIOS update. I had to to hardboot by shutting off the PC subsequent turn on attempts only turns on Power and HD light and fan running but BLACK SCREEN. I called Toshiba Tech support who would only talk to me if I pay out of warranty tech support charge of $49.95. How is it justified for a PC manufacturer to charge a customer for its hardware failure as a result of installing and updating manufacturer sent software update? How can I make this rude people to realize this?
